Part 1: Find the Eigenfunction Expansion
Consider the function f (same as in the previous problem) defined on the interval [0, 10] as follows,
3
x,
f(x)=
x = [0,5],
5
3.
x = [5, 10].
Find the coefficients C, of the eigenfunction expansion of function f,
00
f(x) = co+cn Yn(x),
where yo=1 (which is not a unit eigenfunction), while yn, for n = 1, 2, 3, ., are unit the eigenfunctions of the Regular Sturm-Liouville system
-y" = Ay. y' (0) = 0, y' (10) = 0.
Note:
The constant eigenfunction yo= 1 is not a unit eigenfunction, since yo yo = 10. Therefore, the formula for co is co=
the eigenfunctions yn, for n = 1, 2, 3, ... to be unit eigenfunctions. Therefore, the formula for the coefficients c, is C = fyn-
